NEW DELHI: Arvind Kejriwal, whose AAP has rewritten the grammar of politics in Delhi and may possibly do so elsewhere, on Saturday took oath as Delhi chief minister promising a corruption-free government and new style of governance without arrogance of power.

45-year-old Kejriwal, a former revenue service official, who broke from Anna Hazare’s campaign for Lokpal and scored a stunningdebut in electoral politics winning 28 of the 70 seats, took the oath of office and secrecy at a public ceremony in the historic Ramlila Maidan, the fast venue of the anti-graft campaigners more than two years ago.
